I can't join to any multiplayer game

Hello, again
I have a problem with multiplayer.
I can’t join to any co-op game.
I will connect and nothing happend.
I have Borderlands 2 GOTY edition.

I will be glad if you will try to help me :smile: :smile: :smile:

Did you find any solution to this problem yet? I happen to have the same thing and cant play coop. Restarted Steam, PC, checked firewall, forwarded ports, created custom modem profile, verified game cache etc but I still cant join games. It goes on the loading screen and hops back to the main screen in a few seconds. I would really appreaciate any help.

Yes, i found it delete folder in Program Files/Steam/Steamapps/common/ (the Borderlands 2 folder)
And thats it it works.
